Unrequited love

Sports reporter Nishiwaki Tetsuro (Kenta Kiritani) married Risako (Ryoko Kuninaka), the manager of the American football club he belonged to during his college days, but the relationship between the couple was not harmonious. One day, on the way home from a class reunion with male teammates such as Yukihiro Hayata (Ryohei Ohtani) and Makoto Subai (Masato Wada), Tetsuro and Subai sneaked into the university playground and met Mitsuki Hiura (Miki Nakatani), a former rugby manager. Mitsuki, who exuded an unusual aura, said shocking words - "I killed someone." Later at Tetsuro's house, Mitsuki confesses to Tetsuro, Subai and Risako that she has gender identity disorder. Moreover, Mitsuki, who worked as a bartender in a nightclub as a man, killed a customer who was pestering the waitress Saeki Karari (Anne Nakamura) in an inaccessible place. Tetsuro and others were speechless at first, but with the addition of Kosuke Nakao (Kousuke Suzuki), a former member of the rugby team and former boyfriend of Mitsuki, they decided to protect Mitsuki. Soon, Mitsuki disappeared. In the process of searching for Mitsuki, Zhelang faced distressing facts one after another.
